| Summary: | 碩士 === 國立臺灣大學 === 電機工程研究所 === 84 === This thesis presents the design of three new coplanar waveguide
filters, including the fork type、grounded type bandstop
filters and the fork grounded type bandpass filter. The filters
are built from cascading several sections of quarter wavelength
coupled transmission lines. After a suitable analysis based on
the model decomposition theory, each section is maded
equivalent to an admittance inverter essential in the filter
design. Several design charts are provided in yielding the
geometrical parameters of each section to implement the desired
admittance inverter. By neglecting the eqasi-static equivalent
lumped circuit models of the discontinuities near the points of
two sections, the equivalent models of coupled transmission
lines are evaluated and incorporated into SPICE simulation to
investigate more thoroughly the filter characteristics. The
agreement between simulation results and experimental data
justifies the design procedure and validates the present
analysis approach.
